US Radiator aluminum radiators are made to bolt in exactly as a factory replacement radiator would. Core dimensions are approximately 18 tall X 20" wide. It is made with 2 rows of 1 inch wide tubes on 7/16" centers to provide maximum cooling. All US Radiators can be ordered with a fan shroud, electric cooling fan and thermostatic fan control. The top tank of the radiator radiator can be polished for show or painted to look like stock.The internal automatic transmission cooler is built into the bottom tank of the radiator. This particular radiator can be ordered in a variety of configurations to suit your cooling needs and your budget. Even the largest radiator cannot cool properly without good airflow. Consider replacing your stock 4 blade fan with a six or seven blade fan for optimum cooling.
